DATING-STAMP.

Specification of Letters Patent.

PatentedMar. 6, 1917.

Application filed January 20, 1913. Serial No. 742,993.

To all whom it may concern:

Be it known that I, EMIL C. BUEHRER, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Dating-Stamps, of which thefollowing is a specification.

This invention relates to improvements 1n dating stamps. 1

An object of the invention is to provide means of a strong constructionand minimum number of parts for changing the dates of the stamp, saidmeans being operated entirely from the outside of the housing.

The invention furthermore consists in the improvements in the parts anddevices and in the novel combinations of the parts and devices hereinshown, described or claimed.

The invention is in the nature of an improvement upon the structuresdisclosed in the patents granted to Alexander D. J oslin, Nos. 986,424,dated March 7, 1911, and

1,011,063, dated December 5, 1911, and consists, broadly, in providing amultiple sleeve shaft on which the printing type-wheels are supported,each member of the multiple shaft having fixed thereto one of thetypewheels, and each member being extended to the outside of the housingand provided with means for independently rotating the same, whereby thetype-wheels may be adjusted as desired.

In railroad ticket oflices and especially ticket oflices in large citieswhere tickets are sold for use at a future date, it is essential thatsimple means be provided for adjusting the dating stamp so that thetickets may be stamped with the date on which the same are to be used,and in this connection it is highly desirable that the adjustment orchanging of the type-wheels be efiected without the necessity of liftingup the housing which is found on most of the dating stamps now in use.It is also essential in the interests of economy, that a minimum numberof parts be .used and at the same time maintain a rigid support for thetype-wheels which are subjected to constant hard usage.

One structure which accomplishes the above indicated desirable objects,is shown in the drawings forming a part of this specification, in whichFigure 1 is a partial, verti- 66 of Fig. l.

tially on the line 22 of Fig. 1. Fig. 3 is a transverse, vertical,sectional view taken on the line 33 of Fig. 2. Figs. & and 5 aresectional, detail views taken respectively on the lines 4+4 and 55 ofFig. 3 and Fig. 6 is a detail, sectionalvview taken on the line In thedrawing, the base or main frame of the dating stamp is indicated by thereference 10 and, as customary, is provided at the rear with a pair ofupstanding hinge lugs 11 supporting a pivot pin 12 onwhich 1s swinginglymounted a pivoted housing 13 and a spring-controlled striking arm 1 1having the usual knob 15. normally locked in engagement with the base 10by means of a yieldable member 16 having a catch portion 17 adapted toengage beneath a projecting edge 18 formed on the base 10, thearrangement being such that as the housing is dropped down thecooperating members 17 and 18 will automatically engage and lock theparts together, the engagement being broken, when desired, by means of adepressible push pin 19, (see Fig. 6). Removably secured to the housing13 by means of dowel pins, is the usual printing die-plate 20 carryingtype for printing matter which remains unchanged in the stamping oftickets, said die-plate 20 being provided with a central opening 21through which the type on the type-wheels, hereinafter described,project. The dating stamp is provided with an inking arrangementcomprising a type ribbon 22 adapted to be unwound from a reel supportedby a cross pin 23 by means of a ratchet disk 24 operated, step by step,by a spring controlled pawl 25 oscillated each time the striking arm isstruck. A dragging pawl 26 is provided to prevent any backward rotationof the ratchet wheel 24. and a rotatable cam 27 is also provided adaptedto throw the pawls 25 and 26 out of engagement with the ratchet wheel 24to permit the ribbon to be rewound on the reel at the front of thedating stamp.

The base 10 is provided with a bearing portion. 28 in which is rotatablymounted a multiple sleeve shaft comprising three members 29, 30 and 31telescoped one within the other and each having portions thereof of thesame diameter and all extended to a point outside of the housing andbase. The members 29, 30 and 31 are of different lengths, as shown moreclearly in Fig. 3,

and secured to the outer ends of each of said members are turning knobs32 by means of which said members of the multiple shaft areindependently rotatable. Rotatable with the sleeve or member 31 is aprinting type wheel 33, the same being keyed to the member 31 by meansof a ratchet disk 3 lhaving a tongue 35 which engages a keyway 36 formedin the member 31, it being understood that the ratchet disk 3% isrigidly secured to the type-wheel 33. Two other type-wheels 37 and 38are similarly secured to the members 30 and 29 respectively, of themultiple sleeve shaft, said type wheels 37 and 38 being preferablyseparated by a spacing disk 39. Each of the ratchet disks secured to thetype-wheels 33, 37 and 38 is engaged by a spring controlled detent 4L0,said detents being provided in order to insure the proper alinement ofthe type on the type wheels, and permit the type-wheels to be rotated ineither direction by means of the turning knobs 32. Also supported by themultiple sleeve shaft at its inner end and rotatable thereon, are twoother printing type wheels 41, the same being notched on theirperipheries and adapted to have said notches engaged by yieldinglycontrolled pivoted detents 42, said detents 42 being provided withupwardly projecting finger pieces 43 preferably arranged in differentblanes so that when one of the detents is manipulated the adjacentdetent will not be accidentally moved. If desired, one of the members ofthe multiple shaft may be provided with a groove 4% alining with anopening in the outermost knob 32 by means of which oil can be suppliedto the inner portions of the shaft and the shaft is adapted to be heldin position by any suitable means such as the groove 45 at the inner endthereof and in which takes a screw or pin (not shown).

In practice, the type-wheel 33 is provided with the names of the monthsand the knob 32 secured to the sleeve 31, is provided with suitablecorresponding marks to indicate the months, the type-wheel 38 isprovided with numerals from zero to nine inclusive, and the type-wheel3'? is provided with numerals from one to three inclusive, the knobs 32secured to the members 30 and 29 being also provided with suitable markscorresponding to the numerals on the type wheels 37 and 38 respectively.The type-wheels 41 are provided with numerals ranging from Zero to nine,both inclusive, and are used to designate the year, while the numeralson the type-wheels 37 and 38 are used to designate the days of themonth.

In use, the type-wheels 41 are changed very seldom and whenever it isnecessary to change the position of these wheels, the housing 13 willbelifted, the proper detent l2 depressed and the member 29 rotated,

which will in turn rotate the wheel 41 by friction. ii henever it isdesired to change the position of either of the type-wheels 33, 37 or38, the proper turning knob 32 is rotated, the marks on the knobsindicating clearly the position of the type which are obscured by thetype ribbon 22. With the means above described, it will be seen that thedate may be changed rapidly and easily without lifting up the housing,thus effecting a saving in the time necessary to stamp the tickets withdifferent dates.

Although I have herein shown and described what I now consider thepreferred embodiment of my invention, yet it will be understood that thesame may be embodied in other structures withinthe scope of the claimsappended hereto without departing from the spirit of the invention.

I claim l. A dating stamp comprising, in combination: a plurality ofprinting type-Wheels, a multiple sleeve shaft tothe parts of which saidprinting type-wheels are secured and by which said type-wheels arerotated, one part of said shaft being adapted to be rotated relativelyto a type-wheel carried by and operable by it, substantially asspecified.
